Name: Investigating the speciation of hydrocarbonaceous deposits formed during oxidative dehydrogenation of propane

Description: Natural gas comprising mainly methane, ethane and propane is widely used as a raw material for different petrochemical applications. For example, polyethylene and poly-propylene are produced from ethane and propane, respectively. In this case, these alkanes (ethane and propane) are dehydrogenated over a catalyst that selectively promotes the reaction to alkenes (ethene and propene) which are building blocks for polyalkenes. However, this catalytic process suffers from efficiency due to catalyst deactivation and selectivity issues, thus, it yields undesired side products such as CO2 or coke. We aim to improve this catalytic process by better understanding the surface reaction mechanism and catalyst structure-activity relationships using neutrons at ISIS. This proposal aims to characterise the surface deposits on the catalysts, during ODH and for a deactivated catalyst using TOSCA.
